Upon our arrival we performed 6 month checkups on 2 furnace systems, 4 heat pump system and 1 mini split system for the server room. Flushed and treated the water removal systems, replaced air filters, washed condenser coils using water, cleaned and treated the electrical cabinets then verified systems safety and performance. We found system #6 had a failed air movement system causing the unit to become frozen and unit #5 needs a cleaning on the heat transfer media coil and the air movement system. With the approval from Ronnie we did replace the air movement system on unit #6 and verified its operations. All units are performing to manufacture specifications at this time exempt unit #5 that needs the cleaning performed.
